St John's Island - Hiding hydroids

St John's may not look like much but it has its gems. It also apparently helps to say the magic words "just flip rocks" while doing so.


There are some weird polyp like structures along the foot of this top shell.




Frilly anemones can look very much like vegetables.


Close-up of giant carpet anemone.






The first fruit of the magic words as used by Kok Sheng. The very first rock he flipped after saying them yielded a pair of nudibranchs that look like the Rose nudibranch (Dendrodoris fumata).


Flipping rocks has its dangers though as stinging hydroids lurk in the water. These were found not 2cm away from my fingers while I was flipping a rock but thanks to a rapid warning from Kok Sheng, I avoided much unwanted agony.


The paparazzi treatment.


The unfortunate celebrity, a phyllid nudibranch.


Mysterious patterned layer. It's soft to the touch.


Corallimorphs.




Polyp forests.




More close-ups of polyps.


A Very long ribbon worm *hahaha* (Baseodiscus delineatus). It really is quite long, when its in rubble, one can rarely tell where the 2 ends really are.


Black brittle star found by Kok Sheng.


Common sea star found at the sandy area.


Feeding parts of a Black long sea cucumber (Holothuria leucospilota). Most of them were found chilling out under overhangs quietly feeding away.


Unidentified sea cucumber.


Sometimes crabs are satisfied with just showing you their legs.


Some conchs that are potentially a new discovery.


Timidly observing its observers.


Marauder ants? Marauder ants are known for the large size difference between the minor and major workers.
